LOOM AND FILLING CARRIER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 38,2 at d Nov m 28, 18

Application filed $eptemberl, 1899. Serial No. 729,240. (No model.)

' eration by or through a feeler which feels the filling in the shuttle and before the complete exhaustion of the filling effects the operation of the filling-supplying mechanism. A loom of this type is shown in United States Patent No. 626,187, dated May 30, 1899, wherein the filling is wound at or near the beginning of the spinning operation to form a well-defined projection or bunch for the feeler to work against,such bunch containing sufficient yarn to extend at least once across the lay. The feeler is withheld from effective operation by such bunch until it begins to wind off, and

by such device a very small percentage of waste is involved.

In my present invention the filling-carrier is provided with a longitudinally-movable feeler-stop which is held in the path of and prevents effective operation of the feeler until the filling is exhausted to apredetermined extent, whereupon the stop is released and it is moved by its momentum out of the feelerpath when the shuttle is boxed. The winding. of the yarn is such that when the feelerstop is thus released there will be sufficient yarn still upon the filling-carrier to extend across the lay when the shuttle is thrown into the opposite box.

Figure l is a top or plan View, centrally broken out, of a sufficient portion of a loom to be understood with one embodiment of my present invention applied thereto. Fig. 2 is an enlarged side elevation, partially broken out, of the filling-carrier embodying my invention, the preliminary winding and a portion of the subsequent winding of the yarn being shown. Fig. 3 is a detail in elevation of the head end of a filling-carrier with the feeler-stop in a different position, the fillingcarrier being turned through ninety degrees relatively to Fig. 2; and Fig. 4. is a cross-sectional view of the filling-carrier on the line or in, Fig. 3, looking toward the right.

Referring to Fig. 1, the loom-frame A, breastbeam A the lay A the self-threading shuttle S, the rotatable filling-feeder, (indicated by the letter F, Fig. 1, and comprising connected and suitably-shaped plates to receive the ends of the filling-carriers 1),) the thread-supporting plate 1), filling-end holder 6 studfitransferrerf, mounted thereon,and the shaft a, adapted to be rocked by move ment of the filling-fork in the absence of the filling, may be and are all of well-known construction, like reference letters and numerals being herein used to designate like parts, as shown in Patent No. 626,187, referred to, and, as shown in said patent, the filling-feeder herein is located at one side of the loom and adapted to transfer a fresh supply of filling to the shuttle when in the shuttle-box B, the feeler mechanism located at the opposite side of the loom operating when the shuttle is in the box 13. As in said patent referred to, I have herein shown the filling-feeler a pivotally mounted at a and adapted to pass through an aperture 4 in the front wall of the shuttle-box B (see dotted lines, Fig. 1) when the lay heats up.

If the shuttle be properly boxed, the feeler will pass through a slot 5 in the'side wall of the shuttle and will bear upon the filling 0n the filling carrier or bobbin 1) at each beat of the lay until exhaustion of the filling to a predetermined point, pressure on the feeler tending to swing the arm a on its fulcrum to the left, Fig. 1, to prevent the cooperation of the dagger a with the blade a to thereby effect through suitable intervening mechanism, such as described in said patent referred to, the rotation of the shaft (1 and the operation of the filling-supplying mechanism.

So long as the feeler is engaged before a stud a, mounted adjacent thereto, can pass through an aperture 6 in the wall of the shuttle-box and engage the side of the shuttle the dagger a will be maintained inoperative; but as the filling is drawn off a feeler-stop upon the carrier, and to be hereinafter de- ICO scribed, will be released and moved from the feeler-path, and the stud a will then engage first, so that the arm a" will be swung to the right, Fig. 1, to bring the dagger a into engagement with the blade at to thereby rock the shaft 61'.

Referring to Figs. 2, 3, and 4, the fillingcarrier 1) is represented as provided atits head end b with the usual annular projections or enlargement-s b to enter suitable recesses in the holding-jaws of the shuttle, acylindrical portion 19 of the carrier adjacent the head being shown as provided with a longitudinal recess or slot b extending from one to the other side thereof and intersecting the longitudinal bore Z) of the carrier. The feelerstop, herein shown as a ring or annulus b, is mounted to easily slide longitudinally along the portion 11 of the carrier, said stud being shown in Fig. tas provided with inturned and preferably yielding projections Z1 which enter the slot 12 and serve to limitthe movementof the feeler-stop, the latter beinglarge enough to present a considerable projection beyond the carrier.

Referring to Fig. 4, the projections b are shown as entering the bore 1) of the fillingcarrier, and when the latter is placed upon the spindle in the spinning-frame said projections engage the spindle and hold the stop at the inner or right-hand side of the slot b viewing Fig. 2. When the spinningis begun, enough yarn y, Fig. 2, to extend at least once across the lay is wound on the carrier above the stop b and then the yarn is wound below the stop, as at y. Thereafter the traverse of the yarn both above and below the stop is carried on as usual until the desired amount of yarn has been wound, holding the stop from movement and concealing the same. Each time the shuttle enters the shuttle-box B the feeler a Will contact with the yarn which is Wound over the feeler-stop, the normal position of the latter being in the feelerpath', and this will continue until all of the yarn below the stop has been woven off or unwound. When this takes place and the stop has thus been released, it being re membered that only the preliminary Wind 3 of yarn new remains upon the filling-carrier, the said stop will by its momentum travel to the outer or left-hand end of the slot, viewing Figs. 2 and 3, when the shuttle is boxed in the left-hand end box B, such position beingshown in dotted lines, Fig. 2, and in full lines, Fig. 3, and it will be manifest that at such time the stop will be out of the path of the feeler as the lay beats up, so that the stop a will engage the side Wall of the shuttle and swing or turn the arm a on its pivot a, there being nothing to prevent such. movement. As the arm a is thus swung to the right, viewing Fig. 1, the controlling means for the filling-supplying mechanism, including the plate and the rock-shaft 61, will be actuated, and the operation of the fillingsupplying mechanism will be effected as the The preliminary winding y of filling provides sufficient yarn to be carried across the lay after the effective operation of the fillingfeeler, hcreinbefore described, so that there will be no mispick or thin place in the cloth.

The percentage of filling-waste is by my present invention reduced to a very small proportion and the accuracy and rapidity of operation of the loom and the various parts hereinbefore described are increased.

WhileI have herein shown one practicalembodiment of my invention and have chosen to illustrate it in connection with the feeler adapted to enter the shuttle through an aperture in the side thereof, my invention is not restricted thereto, for from an inspection of the drawings and the description hereinbefore set forth it will be manifest that my invention is equally applicable in any form of loom wherein a feeler is provided to intermitt-ingly feel the filling in the shuttle, said feeler being arranged to operate effectively as soon as a feeler-stop forming a part of or mounted upon the filling-carrier is moved out of the feeler-path upon exhaustion of the filling to a predetermined extent.

So far as I am aware it is broadly new to provide a filling-carrier with a movable feelerstop, and consequently my invention is not restricted to the particular construction and arrangement herein shown and described, as the same may be modified or rearranged in various particulars without departing from the spirit and scope of my invention.

Having fully described my invention, What I claim, and desire to secure by Letters Patent, is-

1. In a loom, a shuttle, a fillingcarrier therein having a longitudinally -movable feeler-stop, the filling being Wound to retain the stop from movement until released by exhaustion of filling to a predetermined extent, filling 5 supplying mechanism, controlling means therefor, and a filling-feeler to govern the operation of said means, the stop when released moving out of the path of and permitting the effective operation of the feeler when the shuttle is boxed.

2. In a loom, a shuttle having a filling-carrierprovided with an annular, longitudinallymovable feeler-stop, the filling being wound to retain the stop from movement until released by exhaustion of filling to a predetermined extent, filling-supplying mechanism,

controlling means therefor, and a filling-feeler to govern the operation of said means, the stop when released moving out of the path of and permitting the effective operation of the feeler when the shuttle is boxed.

3. In a loom, a shuttle, a filling-carrier therein having a longitudinally --n1ovable feeler-stop, a preliminary winding of the filling sufficient to extend across the lay being wound at one side of said stop, subsequent winding holding the latter from movement, filling supplying mechanism, controlling means therefor, and a filling-feeler to govern the operation of said means, the momentum of the stop, when released by exhaustion of the filling to the preliminary winding, moving it out of the path of and permitting effective operation of the feeler when the shuttle is boxed.

4. In a loom, a shuttle having a filling-carrier provided with a longitudinally-movable feeler-stop, a preliminary winding of the filling sufficient to extend across the lay being a wound at one side of said stop; filling-supplyin g mechanism located at one side of the loom, controlling means therefor; and a fillingfeeler at the other side of the loom, to govern the operation of said controlling means, the momentum of the stop when released by exhaustion of the filling to the preliminary winding moving the latter out of the feeler-path when the shuttle is boxed at that side of the loom, permitting operation of the feeler to effect a change of filling when the shuttle is boxed at the opposite side of the loom.

5. As a new article of manufacture, a fillin g-carrier for looms, having a longitudinallymovable feeler-stop thereon.

6. As a new article of manufacture, a filling-carrier for looms, having an annular, longitudinally-movable feeler-stop thereon.

7. As a new article of manufacture, a filling-carrier having a longitudinal recess, and a feeler-stop movable on the filling-carrier and provided with a projection to enter said recess.

8. As a new article of manufacture, a filling-carrier having a longitudinally-movable feeler-stop thereon, and means to limit the movement of said stop.

9. As a new article of manufacture, a filling-carrier having a longitudinal slot near its head, and an annular feeler-stop embracing the filling-carrier and provided with inturned projections to enter the slot.

10. A filling-supply for loom-shuttles, comprising a filling-carrier having a longitudinally-movable feeler-stop, and a yarn mass, a preliminary winding of the yarn of sufficient length to extend across the lay being wound upon the carrier at one end of the path of movement of the feeler-stop, the yarn thereafter being traversed at both sides of the stop and preventing movement thereof.

11. A filling-supply for loom-shuttles, comprising a filling-carrier having a longitudinally-movable feeler-stop thereon, and a yarn mass Wound to hold the stop from movement until the yarn has been drawn off toapredetermined extent.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
